It sounds like science fiction, but if all goes to plan, John Ings, 71, will undergo a radical new surgery called osteo-odonto keratoprosthesis.
The procedure is a unique and complex form of artificial cornea surgery used on patients with the most severe forms of corneal blindness.
It involves removing a tooth and cutting a piece of tissue from it, before drilling a hole, inserting a camera and implanting the tooth back into his right eye.
But the complicated surgical procedure first requires planting the removed tooth into his cheek and leaving it until blood starts flowing through it.
Surgeons then insert the tooth into the old cornea. Some skin is removed from the mouth and placed over the new cornea to seal it.
He will undergo the surgery in a series of four operations, starting next year.
Mr Ings said his progressive blindness has been caused by the herpes virus.
"My vision has been getting worse over the last 16 years to the point where I can't see out of my right eye and hardly at all out of the left eye," Mr Ings said.
"The herpes simplex virus has chewed through the cornea on three separate occasions and it has been patched up with superglue, but now it's all gone frosted."
Mr Ings says if he doesn't have any good teeth left they may use a piece of bone from his hip or skull instead.
"I have been telling my grandkids that they need to look after their teeth because they might have to see through them one day," he said.
In order to complete the procedure, a couple of eye specialists under the supervision of Dr Greg Maloney are travelling to Germany to receive training.
One of the German specialists is then coming back to Australia to supervise the operations.
Mr Ings said the procedure has been conducted overseas since 2004, but his surgery will be an Australian first.
The surgery should happen early next year at the Sydney Eye Hospital, through the Save Sight Foundation, which Mr Ings said has contributed some funding towards the operation.
He will begin preparation for the first of four stages of the operation in a few weeks time at the facility and is optimistic about getting his sight back.
"I'm quite excited about it. I will finish up with a pink eye, but if everything goes I will have 20 20 vision in that eye, which is amazing! I am going to try and get my driver's licence again if it works," he said.
